This was a feature request from a few years back (IIRC from ZanQdo?) to make it
easier to reuse one set of driver variables across several different drivers.
Dev Notes:
* Finally it's done! All that trouble for two little buttons.
* Grr... cmake... grrr!
* Use an RNA enum callback for NLA FModifier types too
* Cleaned up tooltips for these operators in Graph and NLA editors
* Fix update notifiers after adding FModifiers in the Graph Editor
This brings the UI here more in line with the Constraints and Modifiers UI's.
TODO:
* The tooltips/descriptions on the operators now need fixing, as we can no longer
use custom tooltips when defining these buttons.
* The operators need to be fixed to only operate on the active data
This change means that when going from having no FCurves active to having
an active FCurve, the properties panels will not get stuck with only showing
the "View" tab, which is not that useful a lot of the time.
This was only visible on systems with lots of threads and root of the issue
was that we've been pre-allocating too much memory for all the threads.
Now we only pre-allocate data for the main thread and rest of the threads
does allocation on-demand.
This brings down memory usage from 36Gig to 6.9Gig when building spatial
split for the Bunny.blend file on our Intel beast.
Originally regression was happened by the threaded spacial split builder
commit.
Couple of things:
- No need to use string streams to format the version string,
we can do it at compile time and don't bother with anything
at runtime.
- Function declaration was wring and would have caused linking
conflicts in cases when util_version.h was included from
multiple places.
We should have an utility function to get Cycles version so
applications which are linked to Cycles dynamically can query
the version, but that can't be done as an inlined function in
header and would need to be a function properly exported to a
global symbol table (aka, be implemented in a .cpp file).
Now Cycles has its own versioning, that is mainly interesting for external projects, which integrate the engine.
We start with version 1.7.0. Reasons for that:
* The engine is too mature for a 1.0 release.
* We assume that Cycles inside of Blender 2.61 was version 0.1. We count upwards in 0.1 steps, therefore Cycles inside of Blender 2.77 would be 1.7.
We use a common versioning scheme here, with 3 decimals for the major, minor and patch level.
At the moment cycles --version can be used to display the version, easy to parse for external projects. The info will be added to the UI later aswell.
This way we prevent cracks in the model due to discontinuous normals, by using
smooth normals for displacement instead of always getting flat normals after
linear subdivision.

This is a regression since 4310128 which is cased by really bad logic:
there might be dependencies between dupli-objects, which means _if_ we
really want to ensure derived mesh on dupli creation we have to do it
before any matrix is overwritten.
I'm not sure if such derived mesh trick is really the only way to go
without major refactor, but seems simple fix for now will do it.
For some reason other parts of blender importer were assuming velocity
is supported, but actual loader was not aware of that.
Fixes T48064: Adding velocity attribute crashes render
The header which was put to the CMake project is not by any means used
during compilation, it is only used when manually updating CUDA wrangler
from CUDA headers.
This is only the UI change, there is no underlying code change in this commit.

NOTE: this is only the first of many patches towards completing the subdivison
and displacement system in Cycles. These patches will be reviewed and committed
one by one over the coming weeks.

There are couple of reasons:
- Volume shader on hair does behave really weird anyway and it's
not something considered a bug really.
- Volume BVH traversal were only used by camera-in-volume check,
which doesn't really make sense to take hair into account since
it'll be rendered wrong anyway.
Such a removal makes both code easier to extend further (as in,
no need to worry about those traversal for hair bvh) and also
reduces stress on GPU compilers.
This prevents twisted quads from self-intersecting.
This change makes the duplicate surface match the first vertex in the face,
so the diagonal indices match in the face copy.
Previously the logic manager was used as a global variable for SCA_ILogicBrick::m_sCurrentLogicManager,
this request to always update it before run any python script and allow call function like
ConvertPythonTo[GameObject/Mesh]. The bug showed in T48071 is that as exepted the global
m_sCurrentLogicManager is not updated with the proper scene logic manager.
Instead of trying to fix it by updating the logic manager everywhere and wait next bug report to add
a similar line. The following patch propose a different way:
- Every logic brick now contain its logic manager to SCA_ILogicBrick::m_logicManager, this value is
set and get by SCA_ILogicBrick::[Set/Get]LogicManager, It's initialized from blender conversion and
scene merging.
- Function ConvertPythonTo[GameObject/mesh] now take as first argument the logic manager to find name
coresponding object or mesh. Only ConvertPythonToCamera doesn't do that because it uses the
KX_Scene::FindCamera function.

When the Moon is full it was possible to have a dead-lock in task
scheduler's exit() method.
Similar problem was fixed in Blender's task scheduler 3 years ago
in bae2a2c.
Previous fix made another issue even more visible, leading to +1 particle on first vert
and none on last one. This commit should fix both original and new issues.
